TYPE-SIFTER;

SPECIFICATION forming part of Letters Patent No. 228,997, dated June 22,1880.

7 Application filed February 18, 1880.

To all whom at may concern:

Be it known that we,- GEORGE INNIS, of N ewbury, in the county of Essexand State of Massachusetts, and WILLIAM R. WHITMORE, of Newburyport, inthe county of Essex and State of Massachusetts, have invented a new anduseful Type-Sifter, of which the following is a specification, referencebeing had to the accompanying drawings. IO Our invention consistsinacase having coinpartments corresponding to, and being counterpart orreverse in position to. those in an ordinary typecase, and thus adaptedto be employed in combination with the ordinary type-case as atype-sifter.

In the drawings, Figure l is a perspective view of an ordinary type-casehaving our types fterin position thereon previous to reversing the casesto sift. the dirt from the type.

no Fig. 2 is a plan view of the ordinary case; and Fig. 3, a plan viewof our sifter, shown in Fig. 1. Fig. 4 is a vertical section taken online 1 1, Fig. 1. Fig. 5 is a similar section to Fig. 4, but having theperforated bottom of the sifter next to the ordinary case. Fig. 6 showsa vertical section through our type-sifter.

It is well known that in ordinarytype-cases as heretofore constructeddirt collects, to the great annoyance of type-setters. The bottom of thecompartments being close, this dirt is removed with difficulty and withgreat liability to accidentally change the type from one compartment toanother, thus causing great loss of time.

3 5 The purpose of our invention is to obviate these annoyances, and toprovide means for readily cleaning the compartments and the typetherein.

. We make a case, A, having compartments '22, arranged in amanner tocorrespond to those,

' b, in an ordinary type-case, B, and having a perforated bottom, 0.When the compartin the sifter A will be reversed in position to those incase B, as Will be readily understood. This case A may be placedon thecaseB bottom uppermost, as shown in Fig. 1, and fastened thereto byconvenient means, as by the springhasps 0. Then by reversing the twocases the type is caused to pass from the compartments 1) directly tothe corresponding compartments a, and the dirt will sift through theperforated bottomO. The case B may then be removed if desired, leaving'thetype in case A for further 5 5 cleaning or for other purposes.

In the drawings the perforated bottom is shown as of wire-gauze; but anysuitable material may be used having perforations of size and number toaccomplish the desired result namely, to free the type from'dirt andother foreign matter that will pass through the perforations, while thetype is retained.

When wire-gauze or similar material is used we prefer to further supportand keep the same in place by means of the strips or under frame-work D,corresponding to and fastened together with the gauze to the frame andpartitions of the case, as shown.

We claim as our invention- A case having a perforated bottom andcompartments corresponding to and being counterpart or reverse inposition to those in an ordinary type-case, and thus adapted tobeemployed in combination with said ordinary type- 7 5 case as atypesifter, substantially as hereinbeforeset forth.
